After the completion of steel pipe processing, the wall thickness at both ends of the steel pipe will be uneven. Therefore, both ends of each steel pipe must be cut off. Because the length of the defective end of each tube is not the same, it is difficult to determine the specific cutting length when excising. Therefore, it is necessary to measure the wall thickness of the device.
The specific requirements of the test are as follows:
1. Continuous detection and edge feeding. Each steel pipe does not exceed 30 seconds.
2. The length of the test pipe is not less than 500 mm.
3. After the qualified position is detected, the test is stopped and marked on the outer surface of the steel pipe.
4. The quality of the cut steel pipe is within the tolerance range of the national standard of steel pipe, and the precision is 0.02mm.
5. Individually marking the existence of local highs;
6. For steel pipe alarm beyond the set range, the on-site personnel decide whether to release it or not.

The thick wall elbow connecting pipe fitting includes an arc elbow, which is characterized in that there is a straight through connection on the curved elbow. The thick wall elbow is made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metal and plastic. According to the different production process, it can be divided into: welding elbow, punching elbow, casting elbow, etc. The connection mode of thick wall elbow and pipeline is: direct welding (commonly used) flange joint, threaded joint and socket joint.
The structure of thick wall elbow is reasonable, the force of pipeline system is uniform, the pipeline system is simplified, the operation is convenient, the investment is saved, the pipeline resistance is reduced, the pipeline layout is optimized, the operation cost can be reduced, the air flow distribution can be balanced, and the pipeline can be reduced. Vibration and ensure safe operation of equipment and piping. According to the production process, it can be divided into: welding elbow, punching elbow, casting elbow, etc.
